hey ive got a 87 iroc, factory 350 car. was having some problems with rough idle and when under a load, so my friend had a 305 computer with a hypertech chip in it. i decided to try and plug it in and see if it would help. wellit fixed the idle and how the engine ran under a load. its running smooth and good now. but i just wanted to do some research and see what u guys think if i will have a problem or anything with it. will i have to just get another chip burned to my 350 computer, or can i just keep it with the 305 hypertech one. thnks much

its a fluke. take it to a dyno and see what the computer is really doing.
